Packaging Carton

ABSTRACT

The present provides a packaging carton, wherein the packaging carton includes a container. The container includes a base defining a receiving space. A bottom buffering pad is disposed on a bottom surface of the receiving space. A corner buffering pad is arranged in corner of the receiving space, and is dimensioned to match with corner of a workload. Wherein the base, the bottom buffering pad, and the corner buffering pad are inherited with a first buffering property, a second buffering property, and a third buffering property, respectively, wherein the second and third buffering properties are better than the first buffering property. With this, the present invention can effectively reduce the cost of the packaging carton, and which in turn reduce the cost of the product.

FIELD OF THE INVENTION

The present invention relates to a technical field of packaging, andmore particularly to a packaging carton.

The existing processes for manufacturing a liquid crystal display devicegenerally includes the following steps:

Primary Array process: in this process, the whole array substrate andcolor filter substrate are manufactured.

Intermediate Cell Process: in the process, the array substrate and thecolor filter substrate are married or assembled together, filling withliquid crystal, and then cutting into panels of pre-determineddimensions.

Post Module Process: in this process, those panels will be furtherincorporated with other vital components, such as the backlight module,the circuits, and frame so as to complete the manufacturing of theliquid crystal display device.

However, once the panels is prepared with pre-determined dimensions, thepanels have to be properly packed into storage boxes so as to deliver toan assembling factory for final assembling of LCD module.

As shown in FIG. 1, in the packaging carton 10, the glass substrates 12and the but pads 11 are alternatively stacked therein. In order toprevent any occurrence of dust or powder resulted from impact duringtransportation from one place to the other, and consequently andnegatively affecting the air quality of clean-room. It is desirably tohave the packaging carton made from a certain material, such asPolypropylene (also known as PP), which features a certain rigidity aswell as sound impact-absorbing capability. However, the PP is quiteexpensive, and is not beneficial for cost reduction for the finalproduct.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Detailed description will be given with the accompanied drawings.

Referring to FIGS. 2 and 3 which are a perspective and exploded view ofa packaging carton made in accordance with the present invention; and aperspective and exploded view of a packaging carton with the bottomassembled completely, respectively.

As shown in Figures, the packaging carton 20 includes a container 21 anda top lid 22. The container 21 includes a base 211, a bottom buffering,pad 211, and a corner buffering pad 213. The base 211 is defined with areceiving space 23 for receiving a workload therein. The base 211 can beimplemented into a drawer configuration. Alternatively, the base 211 canbe configured by assembling different parts made from engineeringplastic. In general, the engineering plastic parts may have two. In thepresent embodiment, the base 211 is inherited with a first bufferingproperty. In addition, the base 211 is located at outmost peripheral andwhich does not in contact with the workload. In this regard, the base211 can be made from material with certain buffering property, such asthe engineering plastic which is comparably inexpensive, for example,Acrylonitrile butadiene styrene (ABS) or polyethylene (PE). In addition,in order to reduce the material cost while increasing the bufferingperformance, the base 211 can be made from hollowed board.

The bottom buffering pad 212 is disposed on the bottom of the receivingspace 23 of the base 211. The bottom buffering pad 212 is inherited witha second buffering property which can properly protect the corners ofthe workload which are not covered and protected by the corner bufferingpad 212. The bottom buffering pad 212 can be dimensioned to have thesame dimension of the bottom of the receiving space 23 of the base 211,such that the whole bottom of the receiving space 23 can be covered bythe bottom buffering pad 212. In one of the embodiments, the bottombuffering pad 212 can he made from polypropylene (PP) film.

The corner buffering pad 213 is disposed on corners of the receivingspace 23 of the base 211, and which is dimensioned to match with theshape of the corners of the workload. The corner buffering pad 213 isdirectly in contact with the workload. The corner buffering pad 213 hasan L-shaped configuration, and is configured with an L-shaped base board2131 and L-shaped sidewall 2132 which extends upward from the base board2131. In this embodiment, the sidewall 2132 of the corner buffering pad213 can be arranged with a retainer or hook in a surface facing the base211, while the base 211 is arranged with a corresponding buckle toengage with the retainer. By this arrangement, the corner buffering pad213 can he readily and securely attached to the base 211. Of course, andit should be noted that the engagement between the corner buffering pads213 and the base 211 is not limited to what disclosed above. Forexample, the corner buffering pad 213 can be glued to the base 211 orattached thereto with double-sided tape. The corner buffering pad 213 isinherited with a third buffering property. When the packaging carton 20is used to pack the workload, when the packaging carton 20 contains theworkload, the workload is directly supported and protected by the cornerbuffering pads 213 such that during the transportation, the workloadwill not in contact with the base 211 and no damages will beexperienced. In the current embodiment, the corner buffering pad 213 canbe made from material with excellent buffering performance, such as theexpanded polypropylene (EPP). There are totally four corner bufferingpads 213, and each is arranged in a corresponding corner of thereceiving space 23 of the base 211. When the workload is seated into thebase 211, those four corner buffering pads 213 withhold the workloadrespectively. As a result, not only the workload is properly supported,the corners of the workload are also well protected.

It should be noted and specially explained that the third and secondbuffering properties are superior to the first buffering property. It isfor sure that the material with better buffering property will also beexpensive as well. In the present invention, the base 211 which does notdirectly in contact with the workload can be made from material withordinary buffering property, while the bottom buffering pad 212 and thecorner buffering pad 213 can be made from material with excellentbuffering performance. Since the usage of the material in making boththe bottom buffering pad 212 and the corner buffering pad 213 iscomparably small, accordingly, this can readily reduce the overall costof the packaging carton.

Referring to again FIGS. 2 and 3, the top lid 22 is arranged on top ofthe container 21 so as to enclose the container 20. In the presentinvention, the container 20 is used to contain the liquid crystaldisplay panels. Of course, the container is not limited only thereto.

In the current embodiment, the packaging carton made in accordance withthe present invention includes a container configured with baseintegrated with the bottom buffering pads and corner buffering pads.With this arrangement, the bottom buffering pad which has excellentbuffering performance is arranged on the bottom of the receiving spaceof the base, and the corner buffering pads with excellent bufferingperformance is arranged on each of the corners of the receiving space.Both of the bottom and corner buffering pads are directly in contactwith the workload. However, the base which is made from material withcomparably poor buffering performance as compared to the bottom andcorner buffering pad is arranged on the outmost of the bottom bufferingpad and the corner buffering pad. By this arrangement, when thepackaging carton is used to contain the workload, the corner bufferingpads can directly withhold the workload, while the base is indirectlywithholding the workload. In this regard, the base can be made frommaterial of less expensive. Once the cost of the packaging carton isreduced, the cost of final product is reduced as well.
